The Tire Reviews Score is the most comprehensive tire scoring system available. It aggregates professional test data from multiple independent publications, user reviews, and consistency analysis using Bayesian statistical methods, weighted normalisation, and recency-adjusted scoring to produce a single, reliable performance rating.

Methodology & Configuration
Scoring Process
  1. Collect Test Data: Gather results from professional tire tests across multiple publications. Minimum 1 test(s) required.
  2. Normalize Positions: Convert test positions to percentile scores using exponential weighting (factor: 1.2).
  3. Apply Recency Weighting: More recent tests are weighted higher with a decay rate of 0.95.
  4. Incorporate User Reviews: Factor in user review data (minimum 5 reviews). Weight: 15%.
  5. Bayesian Smoothing: Apply Bayesian prior (score: 7, weight: 1.5) to prevent extreme scores with limited data.
  6. Calculate Final Score: Combine all components using normalization factor of 1.1. Max score with limited data: 9.5.

Top 3 Michelin Primacy Alpin Reviews

Given 81% while driving a Ford Fiesta 2009 titanium 1.4 (195/50 R15) on a combination of roads for 20,000 average miles
Bought these on steel rims and used them for last 4 winters. Would love to buy Michelin again. Wear is fantastic, still plenty of mm left. Really feel added safety and grip in cold dry and wet conditions. Also safe as houses in snow, mpg is bit lower than summer tires but I expected and accept the added safety and security in winter months.also not as much feedback or progressiveness as the summer tires. Am a huge fan of winter tires now. For travelling with my family, safety is paramount.

Given 96% while driving a Citroën C5 (225/55 R17 H) on a combination of roads for 12,000 average miles
Have tried several tires and these are with out doubt the best I have tried. Compared to my previous tires (avon) these are amazing. Grip is superb both wet and dry and they are so quite. Cannot see me buying any other tires now that I have used these.

Given 80% while driving a Mercedes Benz c 220 cdi (205/55 R16 V) on a combination of roads for 5,000 average miles
Used over 4 winters in SE France and the alps. Good performance on snow covered roads, but traction easily broken in deeper snow when moving off. Would probably be better on FWD veh

Latest Michelin Primacy Alpin Reviews

Given 89% while driving a Ford Focus mk2 (205/50 R16 W) on mostly motorways for 10,000 spirited miles
2009 I bought these to drive out to the Alps for a skiing holiday, as I understand they are a legal requirement in the area we were going to.
They were exellent. The grip in both loose and packed snow was unbelievable, but they also turned out to be much much better than ordinary Michelin Pilot's in normal British rain and damp as well. Under braking they stop Meters shorter and on corners they grip very well and broke away progressively. In the dry they are fine in normal driving but do not have the absolute grip and turn in of a high performance summer tire. They may be a bit noisier, but not enough to be sure. However as soon as there is a shower of rain they are noticably better than "normal" tires - and I do more driving in the wet than I do on empty dry tarmac. They do not seem to wear any faster than normal either - 10,000 miles, fronts half down and rears "as new".I think that is pretty good...
One superb incident when I left the handbrake on one morning as I drove off on packed snow. The fronts just gripped and we moved off with the (standard) rears locked. I didn't even notice until the back end started waving about as I slowed down for the first bend! Unbelievable. Highly recommended for all year round British driving.

Given 89% while driving a Ford Mondeo (205/50 R16 W) on mostly motorways for 20,000 spirited miles
2008 I bought these to drive out to the Alps for a skiing holiday on my 2.2 diesel Mondeo, as I was told they were a legal requirement in the area we were going to. Ended up leaving them on all Summer and sold them with the car.
They were exellent. The grip in both loose and packed snow was unbelievable, but they also turned out to be much much better than ordinary Michelin Pilot's in normal British rain and damp as well. Under braking they stopped Meters shorter and on corners they gripped very well and broke away progressively. In the dry (June...) they were fine in normal driving but did not have the absolute grip and turn in of a high performance summer tire. They may have been a bit noisier, but not enough to be sure. However as soon as there was a shower of rain they were noticably better than "normal" tires - and I do more driving in the wet than I do on empty dry tarmac. They did not seem to wear any faster than normal either - 20,000 miles, fronts still legal and rears only half down.I think that is pretty good...
2009 I put a pair on the front of my new Focus (2.0Tdi). exactly the same result. One superb incident when I left the handbrake on one morning as I drove off on packed snow. The fronts just gripped and we moved off with the (standard) rears locked. I didn't even notice until the back end started waving about as I slowed down for the first bend! Unbelievable. Highly recommended for all year round British driving.
